Snoop Dogg, RZA and Common to guest-star on The Simpsons' hour-long special

It's the longest episode yet.

Common, Snoop Dogg and RZA are all headed to Springfield for The Simpsons' forthcoming hour-long special. It's their biggest episode to date and it's set to air in January. As the longest-running sitcom in history, it's surprising they've never aired an hour-long show before, but we digress.

Titled The Great Phatsby, the episode will also feature Key & Peele‘s Keegan-Michael Key and Academy Award-nominee Taraji P. Henson and will predictably be a spin on F. Scott Fitzgerald's classic The Great Gatsby.
